Patent GB-793781-A (GB)
Abstract: 793,781. Valves. WANTZ, C. Aug. 30, 1954 [Aug. 31, 1953], No. 25167/54. Class 135. A control device for gaseous fuel burning appliances has a thermostatic valve 182, a timing valve 74, and a gas cock 30 disposed within a single casing 10 and a common actuating element 78 for actuating the timing valve and adjusting the thermostatic valve. On depressing the knob 102 a sleeve 50 lifts a locking-plate 66 out of a cam notch so that the plug cock 30 may be rotated to bring the port 33 into line with the inlet 12 by rotation of the knob 102 acting through the sleeve 50 slidably keyed to a sleeve 54 secured to the valve stem 40. On depressing a knob 104 its spindle 98 abuts and moves axially the spindle 78 carrying the timing valve 74 seating on the open end of the plug cock. Depression of the knob 104 against leaf-springs 148 moves a squared thread 110 out of a recess 120, Fig. 5, in member 114 secured to the knob 102, into engagement with internal threads 122 in member 116 also secured to the knob 102. Rotation of the knob 104 screws the thread 110 into the threads 122 and also winds up the clockwork mechanism 128 a desired amount. After a time interval the clockwork mechanism rotates the threads 110 out of the threads 122 and the timing valve snaps closed under the spring 94. Rotation of the knob 102 and cock 30 also rotates the timing valve through the slidably keyed members 54, 84 and through the member 166, slidably keyed to the timing valve, adjusts the setting of the thermostatic valve with respect to its seat 184 by means of the screw 172. The valve 182 is actuated by a diaphragm 154 connected to a bulb 150. Initial adjustment of the thermal valve is made by removing the knob 102 and sleeve 50, loosening a locking-plate 86 screw fixed to the member 84 and rotating the shaft 78 by means of a screwdriver. The valve 74 may be fixed open by moving threads 110 into engagement with threads 122 and rotating knob 104 in a direction opposite to that for time setting so as to jam the threads. Specification 777,429 is referred to.

Title: Catalytic processes
IPC: B01J19/08
Filed: 1979-12-10
Abstract: At the end of a liquid phase chemical process carried out in the presence of solid particles of supported or unsupported catalyst comprising a magnetic or magnetisable metal, for example a ferromagnetic metal such as Raney nickel, the catalyst particles in the liquid reaction mixture are magnetically flocculated by application of a magnetic field (either continuously or intermittently) the flocculated particles allowed to settle to the bottom of the process reactor and the supernatant liquid withdrawn from the reactor leaving the flocculated catalyst particles in situ in the reactor for further use. The process enables equipment usually supplied external to the process reactor for separation of the catalyst from the reaction mixture to be dispensed with, and catalyst life is increased. The process has applicability to a wide range of reactions in which magnetic catalysts are used, for example hydrogenations, dehydrogenations etc.

Title: Engaging construction, engaged sheet, engagement projection, and engagement structure
IPC: B41L29/12
Filed: 1980-07-24
Abstract: A construction for engaging a sheet to a body e.g. a stencil to a duplicator, which includes an engagement projection protruding from the body and a portion of the sheet formed with an engaging aperture. The engagement projection is formed of first and second columnar portions extending from the body so as to be substantially parallel to each other. A bridging portion joins the ends of these columnar portions remote from the body. The engaging aperture is formed as first and second holes adapted to receive the first and second columnar portions, respectively. An elongated slit opening joins these two holes. The part of the sheet adjacent to the slit opening is elastically deformed only when the bridging portion passes through the slit, and is substantially not plastically deformed.
Patent GB-2056088-A (GB)
Title: Improvements in or relating to nuclear magnetic resonance systems
IPC: G01R33/56
Filed: 1980-08-11
Abstract: The invention is concerned with mapping RF absorption in a body in a medical nuclear magnetic resonance (NMR) imager. The absorption is detected by taking two NMR images by any suitable imaging method, such that the RF pulses for the two images are different but related so that, in the absence of RF absorption, they produce the same image. The two images are composed e.g. by taking their difference. This should be zero but if absorption has occurred the difference picture is a distribution of that absorption. In an alternative arrangement the difference between the images is non-zero but uniform in the absence of absorption.
